Increase smartphone text size through the display settings
Go into Settings, then tap Display, and then Font size. You’ll be presented with a menu from which you can select Small, Normal, Large or Huge. Select the one you want, and the interface and content of certain apps will now be displayed in text that size.
This is our preferred method for making the text on our smartphones bigger, simply because there are more size options available. Huge text in this menu is the same as the ‘large text’ that can be switched on through the accessibility settings.
